is magic develops/changes is more interesting than the magic system itself
what im trying to say is how magic was discovered is used by people and is being developed for purposes leading to new uses is maybe more interesting than the actual magic system and do the people studying magic have simplified understandings on how magic actually works like the case of classical physics. a tentative example would be avatar the last air bender that when kora is the avatar the bending styles are different and use different motions
